Answer:
B. 700
Step-by-step explanation:
the general linear equation formula is as follow:
![y = mx + h](https://img.qammunity.org/2020/formulas/business/college/u0709jmo0jzv35hlgny02o9hdp59u6jygg.png)
Where h is the value at which the formula intercept the Y axis
And m is the slope value, therefore:
![y = -50x + 1,200](https://img.qammunity.org/2020/formulas/business/college/k4x5dc70vrnnxmzjjqit37fvc0rtrpuj8i.png)
if x = 10
![y = -50(10) + 1,200](https://img.qammunity.org/2020/formulas/business/college/anc7zr7uz8excc1473loh2nxjwepwflcab.png)
y = -500 + 1,200
y = 700
This will be the value of the formula when x = 10
